The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved jar closure whereby certain important advantages are attained, as will be hereinafter more fully set forth. i

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure l is a view in perspective illustrating a means for closing a jar constructed in accordance with an embodiment of my invention, the jar being illustrated in fragment;

Figure -2 is a sectional view tially on the line 2-2' of Figure 1;

Figure 3 is a detailed sectional view taken substantially on the line 3-3 of Figure 1; and

Figure 4 isa view in bottom plan of the closure member unapplied.

As disclosed in the accompanying drawing, A denotes a jar, preferably of glass, and which is adapted to have its upper open end sealed by the closure member C. The jar A and member C are preferably made of glass, although it is to be stated that any other material as desired may be used. The under surface of the closure member. C in its peripheral portion is provided with the two concentrically arranged flanges I spaced apart a distance to snugly receive therebetween the neck portion 2 at the upper or open end of the jar A. Fitting within the annular groove 3 provided between the flanges I, is a sealing gasket 4 which bears against the bottom wall of the groove 3 and has contact with the outer edge of the neck 2, as is clearly illustrated in the accompanying drawing. The washer or gasket 4 is provided with an outwardly disposed tongue 5, as is well-known, to. provide means to facilitate the removal of the washer or gasket 4. To

accommodate this tongue 5 when the closure member C is in effective position upon the jar A, the periphery of the closure member C is formed to providean outstanding lug 6 having its under face recessed, as at I, as is believed to taken substan- 25 engagement of the lugs 8 be clearly illustrated in Figures 3 and 4 of the drawing.

The jar A adjacent to its top or open end is provided therearound with the outstanding lugs preierably integrally formed therewith. In the present embodiment of my invention these lugs 8 are four in number and equi-distantly spaced.

The closure member C is held in applied position upon the jar A by a holding or retaining member R. As illustrated in the accompanying "drawing this member R is formed from a single "length of wire 'ofdesired gage and comprises a central'annular member 9 which is superimposed upon the member C. At equi-distantly spaced points therearound the wire comprised in the construction'of thememb'er 9 is pinched to provide a series of radially disposed andoutstanding members Iii. These members H) are of such length as to terminate slightly beyond the periphery of the closure member C and the outer extremities of these arms I0 are continued by the substantially perpendicularly related arms II which are of such length as to extend beyond the closure member C to overlie the upper or open end portion of the jar A. portions of the arms II spaced strands The outer or free end are continued by the I2 connected at their outer extremities bythe outwardly disposed arch mem I2 provide therebetween bers I4. The strands slots I5 into which are snugly received the lugs 8 of the jar A upon requisite turning movement of the member R. Thearch members I4 maintain the strands I2 in desired relation but offer no hindrance or obstruction to the interlocking within the slots I5.

To facilitate the desired turning of the member R to tighten the closure member upon the jar A or to release the closure member, the holding or retaining member R at diametrically opposed points is pinched to provide the upstanding lugs IS with which the blade of a case knife or other suitable elongated member or element may be engaged.

As is illustrated in the drawing, the inner flange I of the closure member C at predetermined points therearound is provided with the recesses or notches IT to facilitate the effective application or removal of the closure member C, and more particularly to break the the jar A when it is desired to remove the closure member C.

From the foregoing description it is thought to be obvious that a jar closure constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and vacuum within facility with which it may be assembled and operated.

I claim:

1. The combination with a jar having lugs extending outwardly therefrom adjacent to its open end; of a closure member for the open end of the jar and a retaining member for holding the closure member to the jar, said retaining member comprising a central annular member to overlie the closure member, outstanding arms carried by the annular member, said arms being of a length to extend beyond the periphery of the closure member, the outer extremities of said arms being continued by substantially perpendicularly related arms of a length to overlie the open end portion of the jar when the closure member is applied, the outer end portions of the second arms being continued by the laterally directed spaced elements providing slots therebetween to receive the lugs of the jar upon turning movement of the retaining member in one direction, and outwardly disposed arch members provided at the outer extremities of said spaced elements and connecting the same.

2. The combination with a jar having lugs extending outwardly therefrom adjacent to its open end; of a closure member for the open end of the jar and a retaining member for holding the closure member to the jar, said retaining member comprising a central annular member to overlie the closure member, outstanding arms carried by the annular member, said arms being of a length to extend beyond the periphery of the closure member, the outer extremities of said arms being continued by substantially perpendicularly related arms of a length to overlie the open end portion of the jar when the closure member is applied, the outer end portions of the second arms being continued by the laterally directed spaced elements providing slots therebetween to receive the lugs of the jar upon turning movement of the retaining member in one direction, and outwardly disposed arch members provided at the outer extremities of said spaced elements and connecting the same, the annular member, arms, spaced elements and arch members being formed from a single length of material.

3. The combination with a jar having lugs extending outwardly therefrom adjacent to its open end; of a closure member for the open end of the jar and a retaining member for holding the closure member to the jar, said retaining member comprising a central annular member to overlie the closure member, outstanding arms carried by the annular member, said arms being of a length to extend beyond the periphery of the closure member, the outer extremities of said arms being continued by substantially perpendicularly related arms of a length to overlie the open end portion of the jar when the closure member is applied, the outer end portions of the second arms being continued by the laterally directed spaced elements providing slots therebetween to receive the lugs of the jar upon turning movement of the retaining member in one direction, outwardly disposed arch members provided at the outer extremities of said spaced elements and connecting the same, and substantially diametrically disposed and upstanding lugs carried by the annular member to provide means to facilitate turning movement of the retaining member.
